Fly ash geopolymer concrete material and preparation method thereof
The invention discloses a fly ash geopolymer concrete material and a preparation method thereof.The fly ash geopolymer concrete material is prepared from cement, slag, fly ash, water, water glass, hydrogel and alkali-activated liquid, fly ash serves as the raw material, and the fly ash geopolymer material is synthesized at the normal temperature through the excitation effect of the alkali-activated liquid; the coal ash geopolymer concrete material is synthesized after the coal ash geopolymer material is fully mixed with the cement, the water, the water glass and the water glue, the slag can improve the synthesis speed of the geopolymer material and improve the strength of the material, the uniformly mixed slurry needs to be guided into a test mold to be molded and cured, and the compression resistance and bending resistance indexes are tested. According to the method, the actual engineering application of the fly ash geopolymer concrete in the reinforcing and repairing directions is researched by observing the crack propagation mode of the transition interface and analyzing the crack generation mechanism, and a reference basis is provided for the actual engineering application.
本发明公开了一种粉煤灰地聚物混凝土材料及其制备方法，其原料包括：水泥、矿渣、粉煤灰、水、水玻璃、水胶、碱激发液，本发明以粉煤灰为原料，通过碱激发液的激发作用，在常温下合成粉煤灰地聚物材料，而粉煤灰地聚物材料与水泥、水、水玻璃、水胶充分混合后将合成煤灰地聚物混凝土材料，而矿渣可以提高地聚物材料合成速度，提高材料强度，而均匀混合后的浆体需导入试模中成型养护，测试抗压、弯曲抗折指标，本发明通过观察过渡界面裂纹扩展方式，分析裂纹产生机理，研究粉煤灰地聚物混凝土在加固与修复方向的实际工程应用，为实际工程应用提供参考依据。
